TheInstitute of Environmental Sciences and Technology (IEST) (Mount Prospect, IL) has announced that on September 15, 2000, the next document from ISO Technical Committee 209, ISO Standard 14644-2, “Cleanrooms and Associated Controlled Environments – Part 2: Specifications for Testing and Monitoring to Prove Continued Compliance with ISO 14644-1” will become available. IEST serves as Secretariat for ISO T/C 209 which developed the paper as part of a series of 11 documents to serve the needs of the global contamination control community.

ISO Standard 14644-2 specifies requirements for monitoring and periodic testing of a cleanroom or clean zone to prove its continued compliance with ISO Standard 14644-1 for the designated classification of airborne particulate cleanliness. The control of airborne particulate contamination levels is an important factor in several industries including aerospace, microelectronics, pharmaceuticals, medical devices, health care, and food, as well as many others.

Successful standardization hinges on the achievement of widespread agreement. ISO/TC 209 reflects a cooperative effort of more than 1,000 professionals from 34 nations.
